The Siemens SENTRON 3VA2110-5JP32-0HH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It's configured for line protection with a built-in communication function, a shunt trip (STL), and a complement of 2 auxiliary switches plus 1 trip alarm switch (HQ). The interrupting ratings climb to 187 kA at 240 V and hold at 121 kA through 440 V, then step down to 75.6 kA at 500 V and 3.7 kA at 690 V.
What the interrupting ratings mean for panel coordination
The 187 kA SCCR at 240 V and 121 kA at 415/440 V place this breaker in the high-interrupting-capacity tier of the SENTRON 3VA platform. At a typical 480 V distribution voltage (the 500 V row), the 75.6 kA rating still covers most industrial service-entrance and feeder applications. The 3.7 kA at 690 V is the tail-off point — adequate for 690 V motor control centers with low available fault current, but not for high-fault 690 V utility ties. For selectivity studies, the 100 A frame with these interrupting levels coordinates cleanly downstream of a larger 3VA frame or a SENTRON 3WL air breaker.
Panel fit and integration
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a 3-pole frame that fits standard SENTRON mounting plates and panel cutouts. The supplied basic switch is order code 3VA21105JP320AA0. The shunt trip (STL) allows remote tripping from a PLC or emergency-stop circuit; the auxiliary switches (2 form-C) and the trip alarm switch provide status feedback for the control system. The communication function supports integration into a higher-level monitoring architecture, though the protocol is not specified in this variant's basic data.
